Description

Verfahren zur Herstellung starkwandiger Körper aus keramischer Masse durch Gießen Bei den jetzt bekannten Verfahren zum Gießen von Körpern aus keramischen Massen lagert sich die Gießmasse in verhältnismäßig dünner Wandstärke an der Gießform ab. Bei Körpern, die für technische Zwecke Verwendung finden sollen, genügt diese Wandstärke für gewöhnlich nicht; sie muß deshalb, will sie den in mechanischer und elektrischer Beziehung an sie herantretenden Beanspruchungen den nötigen Widerstand leisten,- wesentlich größer gehalten werden.Process for the production of thick-walled bodies from ceramic mass by casting In the now known method for casting bodies made of ceramic The casting compound is stored in a relatively thin wall thickness on the casting mold away. For bodies that are to be used for technical purposes, this is sufficient Wall thickness usually not; she must therefore, she wants the mechanical and electrical relationship to them approaching stresses the necessary resistance afford - be kept much larger.

Starkwandige Körper lassen sich in einem Guß infolge Lunkerbildungen und Nichterhärtung im Innern nicht fehlerfrei herstellen.Thick-walled bodies can be cast in one go due to the formation of cavities and non-hardening inside do not produce flawlessly.

Verfahren, diesen übelstand durch" Einbringung eines entsprechenden Kernes zu beseitigen; haben nicht zu den gewünschten Erfolgen geführt.Procedure to remedy this evil by "bringing in an appropriate Eliminate core; have not led to the desired success.

Gemäß dem den Gegenstand der Erfindung bildenden Verfahren, welches auf beiliegender Zeichnung in Abb. i und 2 an einem Ausführungsbeispiel veranschaulicht ist, wird die gewünschte größere Wandstärke des zu gießenden Körpers erfindungsgemäß dadurch erzeugt, daß zunächst auf den Fuß i des Kernes ein ebenso wie der Kern beispielsweise aus Gips bestehender Mantel 2 kleineren Ausmaßes gestellt und alsdann in den zwischen Kern und Mantel 2 entstandenen Hohlraum 3a die Porzellan- o. dgl. Masse gegossen wird (Abb. i). Nachdem die Masse etwas fest geworden ist, wird der bis jetzt verwendete Mantel 2 durch einen größeren, 4, (Abb.2) ersetzt und dadurch der auszugießende Raum 3b zwischen Kern und Mantel vergrößert, so daß nach Ausgießen des Hohlraumes 3b ein Körper von wesentlich größerer Wandstärke entstanden ist. Die hinzugegossene Porzellanmasse hat sich hierbei mit dem zuerst hergestellten Guß innig verbunden, ohne daß zwischen beiden Porzellanschichten bzw. in diesen selbst ein schädlicher Raum entstanden ist.According to the method forming the subject of the invention, which Illustrated on the accompanying drawing in Fig. i and 2 using an embodiment is, the desired greater wall thickness of the body to be cast is according to the invention generated in that first on the foot i of the core as well as the core, for example made of plaster of paris coat 2 made of smaller dimensions and then in the between Core and shell 2 created cavity 3a, the porcelain o. The like. Mass poured will (Fig. i). After the mass has solidified, the one that has been used up to now will be used Sheath 2 replaced by a larger one, 4, (Fig.2) and thus the one to be poured Enlarged space 3b between core and jacket, so that after pouring out the cavity 3b a body with a significantly greater wall thickness has arisen. The added Porcelain mass has been intimately connected with the first cast, without a damaging one between the two porcelain layers or in them Space was created.

Die Wandstärke des Porzellankörpers kann natürlich durch Verwendung weiterer Formmäntel noch vergrößert werden. Auch kann die Form des herzustellenden Körpers sowie die Art seines Materials und auch des die Feuchtigkeit ansaugenden Materials der Gießform von der hier beschriebenen abweichen.The wall thickness of the porcelain body can of course by using further form jackets are still enlarged. Also can be the shape of the to be manufactured Body as well as the type of its material and also that which absorbs the moisture Mold material differ from that described here.

PATENTANSPRUCH: Verfahren zur Herstellung starwandiger Körper aus keramischer Masse durch Gießen, dadurch gekennzeichnet, daß der zwischen Kern (i) und Formmantel (2) entstehende Hohlraum (3a) nach -seinem Ausgießen, aber vor völliger Erstarrung der Masse durch Ersatz des ersten kleineren Formmantels (2) durch einen größeren (4) erweitert und alsdann auf den ersten Guß zwischen diesem und dem erweiterten Hohlraume neue Masse gegossen wird.PATENT CLAIM: Process for the production of rigid-walled bodies ceramic mass by casting, characterized in that the between core (i) and mold shell (2) resulting cavity (3a) after - its pouring, but before complete Solidification of the mass by replacing the first smaller mold shell (2) with one larger (4) expanded and then on the first cast between this and the expanded Cavities new mass is poured.
